Assembly structure for speaker system
An assembly structure for a speaker system includes an iron grille, a speaker frame, a plurality of magnets and a plurality of pads. The speaker frame is covered with the iron grille and includes a plurality of through-holes on one face thereof. Each of the through-holes includes a first receiving portion and a second receiving portion. The speaker frame further includes a plurality of magnets each received in the first receiving portion of a respective one of the through-holes. The speaker frame further includes a plurality of pads each received in the second receiving portion of the respective one of the through-holes.
This is a continuation-in-part application of U.S. patent application Ser. No. 12/823,196 filed on Jun 25, 2010, now abandoned.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention generally relates to an assembly structure of an iron grille and a speaker frame for a speaker system and, more particularly, to an assembly structure of an iron grille and a speaker frame for a wall speaker system or ceiling speaker system.
2. Description of the Related Art
A wall speaker system or a ceiling speaker system generally includes a speaker frame and an iron grille to be attached on the speaker frame.
Therefore, it is desired to improve the conventional assembly structure of the speaker frame and the iron grille for the speaker system.
SUMMARY OF THE INVENTIONIt is therefore the primary objective of this invention to provide an assembly structure for a speaker system which enables an iron grille to be closely attached on a speaker frame of the speaker system.
It is another objective of this invention to provide an assembly structure for a speaker system which prevents magnets from coming off a speaker frame of the speaker system.
The invention discloses an assembly structure for a speaker system which includes an iron grille, a speaker frame, a plurality of magnets and a plurality of pads. The speaker frame is covered with the iron grille and includes a plurality of through-holes on one face thereof. Each of the through-holes includes a first receiving portion and a second receiving portion. The speaker frame further includes a plurality of magnets each received in the first receiving portion of a respective one of the through-holes. The speaker frame further includes a plurality of pads each received in the second receiving portion of the respective one of the through-holes.
The present invention will become more fully understood from the detailed description given hereinafter and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
In the various figures of the drawings, the same numerals designate the same or similar parts. Furthermore, when the terms “first”, “second”, “third”, “fourth”, “inner”, “outer”, “top”, “bottom” and similar terms are used hereinafter, it should be understood that these terms have reference only to the structure shown in the drawings as it would appear to a person viewing the drawings and are utilized only to facilitate describing the invention.
Referring to
Under the structure, the iron grille 2 may be magnetically attracted by the magnets 3 in a proper manner so no gap exists between the magnet 3 and the iron grille 2. In other words, the iron grille 2 is strongly attracted by the magnets 3 so that the iron grille 2 is closely attached on the speaker frame 1. In addition, through the use of the pad 4, the magnets 3 may be prevented from coming off the speaker frame 1. The magnets 3 and the pads 4 may be coupled together by way of adhesion or engagement.
Referring to
The proposed assembly structures are not only easy to proceed but also can keep the magnet firmly and enhance its magnetizing force.
Although the invention has been described in detail with reference to its presently preferable embodiments, it will be understood by one of ordinary skill in the art that various modifications can be made without departing from the spirit and the scope of the invention, as set forth in the appended claims.
Claims
1. A assembly structure for a speaker system comprising:
- an iron grille;
- a speaker frame having a first face covered with the iron grille and including a plurality of through-holes extending from the first face through a second face, wherein each of the plurality of through-holes includes a first receiving portion and a second receiving portion, with the first receiving portion being intermediate the iron grille and the second receiving portion, wherein the first receiving portion has a diameter smaller than a diameter of the second receiving portion, with a shoulder defined between the first and second receiving portions;
- a plurality of magnets each received in the first receiving portion of a respective one of the plurality of through-holes and abutting with the iron grille with no gaps; and
- a plurality of pads each received in the second receiving portion of the respective one of the plurality of through-holes, with the diameter of the first receiving portion being smaller than a diameter of each pad, with the plurality of magnets attaching the iron grille on the speaker frame, with the plurality of pads enhancing a magnetizing force of the plurality of magnets.
2. The assembly structure for the speaker system as claimed in claim 1, wherein the speaker system is a wall speaker system or ceiling speaker system.
3. The assembly structure for the speaker system as claimed in claim 1, wherein the plurality of pads is made of iron.
4. The assembly structure for the speaker system as claimed in claim 1, wherein the first receiving portion includes an inner face coated with an adhesive.
5. The assembly structure for the speaker system as claimed in claim l, wherein the plurality of magnets and the plurality of pads are coupled with each other by way of adhesion or clipping.
6. The assembly structure for the speaker system as claimed in claim 1, wherein the magnets and the pads are coupled with each other by way of clipping.
7. The assembly structure for the speaker system as claimed in claim 1, wherein a bent portion is formed on an outer edge of each of the plurality of pads and extends into the speaker frame from the outer edge to the iron grille and outwardly of the first receiving portion.
8. The assembly structure for the speaker system as claimed in claim 7, wherein the bent portion is formed at an outmost part of the outer edge.
9. The assembly structure for the speaker system as claimed in claim 7, wherein the bent portion reaches the iron grille.
